可以用来参考学习区块链
- 定义区块链
- 挖矿,检查区块链完整性
- 区块链防篡改
- 钱包
- 交易
挖矿开始.... 第一个区块 第2个区块check->true 第3个区块check->true blockLink-> [{"data":"block1", "preSign":"0", "sign":"000004b63b4170f0c1088a0d300570bac54e5109154312efafb9a07c561dd312", "wkc":2031324 },{"data":"block2", "preSign":"000004b63b4170f0c1088a0d300570bac54e5109154312efafb9a07c561dd312", "sign":"0000099a324fe0a7343caa63947bb22b4fd07b7671e8d9958d73df75a6a7f88a", "wkc":41270 },{"data":"block3", "preSign":"0000099a324fe0a7343caa63947bb22b4fd07b7671e8d9958d73df75a6a7f88a", "sign":"000008492aef8361981e0f7ec755bc81745d4637c916925aae5fa3df5d710dde", "wkc":12568 } ]
